Dexx is the youngest of two brothers of a working, single mother.
He became a mechanic.
His Brother, Mark
Mark raped a woman while in college and got away with it. A demon possessed him and gave him his Hell on Earth. Mark committed suicide, spouting about demons.
Dexx became a demon hunter after he discovered the existence of demons was real.
A Dark Path
Of course, demons weren't the only thing Dexx discovered.
He uncovered all sorts of supernatural creatures.
And he learned to take them all down.
